The basic purpose of topographic surveys is to find accurate data about the natural and man-made features of the land in question. It also gives information about the elevation of the land. First the data are collected through physical surveys and measurements, and depending on the raw data collected from the site three dimensional maps are prepared. At first horizontal and vertical controls are established, and these controls act as the framework of the whole boundary surveys. In the next step horizontal location and elevation of the ground are pointed which is then used for plotting the map. Locating the natural, as well as man-made features of the land makes the next step. Computing distances, volumes, angles and drawing the maps make the final stage.
Before a project can start it is necessary to have the full information about the land on which it is going to take place, and topographic survey provides all the topographical information such as any man-made or natural structures on the place and also the ground elevation of the land. These factors have significant implications on the total planning and execution of the project. The budget assigned also depends on the as-built condition of the land. So a perfect topographic survey bears immense importance. With the application of the latest technology topographic surveys can be completed within minimum time and the reports generated are highly accurate.
